rnnrrnva raauna'rmc momma To all whom it may con/cervix :Be it knownthat I,' HEINRICH TOLLE, a citizen of Germany, residing at Villingen,Baden, Germany, have invented certain new I and useful Improvements inPrinting Tabulating Machines of which the following is a full, clear,and exact description.

This invention relates to a computing machine in which the setting oradjustment 1 of the counters is effected by reci rocating toothed racks.The invention has or its object to provide such counter o cratingmechanism with reciprocating rac s, which will be accurate and positivein operation and at the same time present a compact structure. It isnecessary for this purpose that the counter operating toothed racks aremaintained free from all the projections thereon. In accordance withthis invention this result is achieved by actuating the toothed racksfor individual computations through the intervention of oscillatinglatches which are caused to mesh atdiderent phasesof their oscillatorymove- 26 ment, so that,'depending on the particular time of j.enmeshment .of the latches the toothed .Ii'acks will move through alonger or shorter path and will thereby impart to the counters acorrespondingly larger or 30 smaller movement of "rotation.

For printingisums and for resetting the counter wheel io zero a specialarrangement is which; taking intoconsideration the compactness of theentire structure, must be of such nature that. the actuating mechanismfor the toothed racks will take up no more space in a transversedirection than the toothed racks. improved machine this condition is metby 40 providing a system of pusher bars or rods in extension of thesetting toothed racks for actuating said racks for the sum printingoperation and for re-seating the counters to zero position. Fig. 1 is asectional view of the complete machine taken just inside one of the sideplates thereof. i

Fig. 2 is a similar sectional view with parts omitted in order to moreclearly show the operation of the adding and tabulating parts of themachine.

Fig. 3' is a sectional view showing the operating parts utilized intaking sub-totals or intermediate totals.

Fi s. 5 and 6 are enlarged detail views showing the latch mechanism forthe racks respectively in latched and unlatched position. I

Fig. 6 shows the unlatched osition of the parts just after a rack hascon set by the latching devices.

lt willdoe understood that the machine can include an number ofaccumulatin sections. in which case these sections wi be identical inconstruction. For each sec tion of the machine there are threeoperating' ke s designated respectively 29, 29 and 29. (ey 29 isutilized or setting the machine in operative con ition tor str'aigrhtadding. Key 29" is a s'ub-total key. which isdepressed at the end of theaddition of items from agroup of cardsto cause the machine to take asub-total and then go on accumulating without clearing the counter. Key29, on the other hand, is a total key. It is depressed at the end of theaddition of a roup of cards to cause the machine to print a total andcausethe accumulator to be'cleared. Inasmuch as the accumulatingmechanism on the difierent sections is identical one section alone willbe described, it that duplicate mechanism will be provided for the otheraccumulating sections dr in case the machine includes only oneaccumulating section only one set of parts will be needed.

The tabulating machine comprises two side plates and the addingmechanism is built in therebctween. This is shown in Fig. 1 of thedrawings, one of the side plates being removed for the purpose. Theadding mechanism is arranged on the side plate 1 shown in -the drawingsand comprises a stationary plate 2anda movable slide 3 thereon.

tens-counting. mechanism control and 'oonsists mainly of the controllevers 4, release lever 5, arresting lever 6, and the lifting lever 7.The counter rollers 8 and their actuTiEing wheels 9 and 10, as well asthe release lever 11. the safety locking lever 12 are arranged on theslide 3. The latter by the lever 13 through the intervention of theprojection or abutment 14, when a dog member 16 resiliently secured tothe lever 13 is set by the key 29 (Fig. 2} through the rod 15, in suchmanner that in its upward movement the dog member 16 will carr alonjection 14 on the sli e 3. n addition to the lever 13 there is providedanother lever 18 (F ig. 4) similar in its function to the lever 13 butcontrolled by a differently shaped cam disc 19 and consequentlyoperating at different times from the lever 13 to raise and lower thslide 3 The dog .member 18' of the lever 18 is actuated from a specialbar or rod 20 throu h the intervention ofa key-129 (Fig. 4). in additionto the rods or bars 15 and 20, other barsor rods 23 and 24 operate inthe same guide bearings 21 and 22 (Figs. 1 and 3). Bar or rod 23(Fig. 1) carries at its right a roll 26 which may drop into a notchformed in a crank disc 27. When this notch isvreached bar or rod 23 ismoved to the right under-the influence of spring 28 and the locking hook28 having a fork and pin coupling therewith releases the key levers 29,29, Q The p reference character 29 refers generally to These are givenfurther dethe key. levers. tail reference letters 29, 29", or 29:depending. upon their function. The key levers are however maintained inthedepressed position by means 30,30; 30", 30' rotating simultaneouslyabout a shaft 25. In view of the simultaneou-s. ere on of the lockingmembers 30,

30", etc. the depression of a new key releases all previously depressedkeys. The bar 24 (Fig. 3) carries a pin Maud-transmit's the pressure ofthe lrcy 29", through the intervention of a lever 32 and'rod 33, toa

bell crank lcver 34 which is adapted to engage a pin in the slide 3 andto raise the adding mechanism. In this position the wheel 10 engages atoothed bar or rack 35, which by means of a pin 36 sets the t pesegments 52, which latter may be 'loc ed prior to printing by a lever37. A special arm on this lever places a colored ribbon in front of thetypes, by means of a rod 38. while said types are being set. The lever37 is actuated through the intervention of the intermediate lever 39from the bell crank lever 40, which is in turn operated by the speciallyformed cam disc 62. The toothed bar or rack receives its movemcnt fromthe reciprocatingcarriage 41,1the

latter being: actuated from the cam disc 42 through the intervention ofthe large bell crank -lc\'er 43. The coupling of the carriage 4i and thetoothed rack 35 is eflected by the multi-toolhed locking hook 44 whichis adapted to be actuated by magnets 47 through the intervention oflevers 45 and 46 to engage the teeth of the rack 35. In extendedalignment with the rack 35 is arranged a rod 48 under the influence of aspring 49 and adaptcdto be held back by an with it the proof beveledlocking members,

arresting or locking lever 50, until released by the and 29". Thismovement of the lever 50 is transmitted (by a through. setting rod 51'passing along side of the rods- 48 and 35) to a type segment similar toand adjacent the type segments 52, which segment then causes the;'printing of' an indication of the manner of use for which the machinewas set. In view of the different distances between the points ofengagement of the rods depression of predetermined keys 29 53 and 54 andthe centre of rotation of the operative movementto, their originalpositions by the carria e 41 through the aid of the lever 55 rotata 1ymounted 'on'the carriage 4i and moving in-an additional path by thesliding of its inclined surface on the in The rods or levers 5T, 58, 59,60 serve to withdraw after each excitation of themagnets 47 suchstructures as may cling to tliemagnets. .This rod or lever system isactuated from a'pin on the lever 13.

The operation of the tabulating machine in its various individual usesis as follows:

a 1% Adding and ta bulatz'ng (Fig. 2).

who. the key 29'- is-depressed the rod 15 1 moves to the right. The (10member 16 is is positioned under the projectiono'r abutment 14 of thethereby swung upward an counter mechanism slide 3. If the machine is nowoperated the two cam discs 42 and 61 will rotate in the directionindicated -by the arrows, on a ratio of one to one. In this manner theroll of the bell crank lever 43 is moved downwardly and the carriage 41is thereby moved from left to right. At the same time a contact isclosed in known manner (see Hollerith Patent No. 945,236. dated January.4, 1910) in the'card'feeding arrangemcntfi which contact is held closedwhile.a card is passing through the machine. When a countingposition orperforation is reached in. the card the circuit oi one of the magnets4iv will be completed (as in Hollerith) and the carriage 41 coupied withone ofthe rack, bars 35. Each magnet for a corresponding cardcolumn isheld energized while counting takes place as is usual. The movement ofthe armature of the magnet 47 is transmitted through the levers 46; 45to the coupling member 44 which engages the rack 35 and carries the samealong through a path the extent of which depends on the position of thecountingpoint or perforation in the card. Dur ing this forward movementthe rack 35 effects the setting of the type segment 5'2,

After the carriage 41 has completed its movement to the right, the lever37 which has to this moment been kept out by the levers 39 and and bythe cam disc 62 (Fig. 3), is now released for a short period. The typesegment 52 is thereby centralized to effect proper alignment of thetype, and the colored ribbon rod 38 moves the colored ribbon to theleft-in Fig. 1 to the type. .At.

this moment the type is printed in known manner on a passing papersheet. In the meantime also the cam disc 61 (Fig. 2) has begun to liftthe lever 13 and has thereby caused the engagement of the intermediatewheel 10 and the toothed rack 35, while the roll of the bell crank leverwas passing over a'concentric portion of the cam 42, thereby maintainingthe rhcks 35 at rest for printing. This movement of the lever 13 is transmltted through the system of rods or levers 60, 59, 58,57 to the leverand the coupling between the members 44 and 35 is thereby released. Thisstep is taken to 'ensure that no armature clings to an electromagnetafter'the circuit of the magnets is broken. The carriage 41 now movesidly back a certain distance under the action of the rising part ofthecam disc 42, such disumn.

taiice corres onding to the complementarv number of t e perforation inthe card colber 44 therebyengages the projection on the rack 35 andreturns the rack to its zero osition. In this manner the same number 1stransferred to the adding roll 8. If now the number 9 is exceeded, thetens-arrangement is brought into operation under the influence of therelease'levers 11 and 5. and its operation is completed upon the returnof the adding mechanism to rest.

The-machine is thus returned to its original position and beginsaddition and tabulation of the next card column. A

If a contact arrangement is usedwhich in place of the time contact, suchas assumed above, establishes a momentary contact, i. e., 1

one which differentiates the.numbcrs not by the durationof the currentimpulses but by closing the contacts at different times. and in whichthe duration of individual contacts may be less than. the" timenecessary for effecting the registry of a unit in the counter mechanism,such modification is taken care of'by the provision of arresting orlooking levers 69 (Figs. 5, 6), the arrange ment being such that thecoupling between the rack3 5and carriage 41 is maintained until thelatter has completed its operative movement.

The ope ition is then. as follows: If the coupling member is actuated bythe magnet 47 through the aid of the intermediate lever 45, the latteris prevented from dropping by the lever 69 (Fig. 5), until the carriage41 has completed its movement to the right.

The shoulder of the coupling mem- At that moment the pin 70 secured't0the .carriage 41 releases the lever 45 (Fig. 6),

and the arrangement is contact;

The machine has added a row. of numbers and is restrained by a stop camor has been brought to rest by the completion of thecom uting operation.Upon depression of the ey 29" the rod 24 is moved to the right. Thismovement on the one hand, couples the adding mechanism with the toothedrack 35, and, on the other hand, it looks the levers 45 through theintervention of the upper nose of the lever 32, thereby reventing theengagement of the cou lngs 4'4 through accidental current i mpu sea. Thedepression of the key also causes the/lever 50 to move outwardly andtherehyto release the spring bars 48. The latter now follows the lefttoright movement of the carriage 41 caused .by the rotation of the camdisc 42. The racks 35 are next broughtto the po si'tionnvith theirprojection 63 bearmg on the couplings 44 and they rotate the addingwheels 10 backwards until thenoses prepared for a new thereof lieagainst locking hooks,.i. e., until the adding mechanism is brought tothe zero 7 thereby brings the previous sum back to the I addingmechanism. in view of the slidirlg of the inclined face of the lever 55on the pin 56, the pin 64 moves through a longer path than the carriage41 and there- .hv releases the bars 48 from the rack 35.

The machine remains at rest. in this position and 'is ready to performother functions.

3. To talizing and zeroizing of the sou rater mechanism Fig.4.

If it is desired to print the total at the end of a column and to cancelthe cumin the addmg mechanism, so that the latter may be ready toperform a new addition, the operation of the machineis similar to thatfor taking intermediate sums, except that the coupling between thetoothed rack and the counter roll isreleased when the latter is in thezero osition. In this operation, steps must be talzen to prevent thetoothed racks, which are'suddenly released and which are under theinfluence of the spring 49, from accumulating the complementary numbersof the sum. The timely release of the engagementhetween the toothed rack35 and the toothed wheel 10 is effected not by the release of thekeysproper, as in the print ng of intermediate sums. but, as in theadding operation, the key 29' causes the rod 20 to move to the'right andthe lever'lS is pushed under the post 17, whereby, in the continuedoperation of the machine, the cam disc 19 immediately causes theengagement of the toothed wheel 10 and rack which engagement ismaintained until the carriage 41 has completed its movement totherig'ht. By the displacement of the rod 20 the lever 57 1S pressedagainst the lower. ro'ection of the lever 45 holding the latter ee Asthe'toothed racks 35, which are under the influence of thespring 49 andwhich until now have been restrained by the toothed wheels 10 (whichlatter have rotated until their noses rest on the locking book 12),
